A container includes a hollow truncated body made of paper material. The container body is tapered off so that the bottom end opening of the body is larger in size than the top end opening thereof. The top end of the body has an edge portion which is widened outwardly to a predetermined degree. The cover is bonded to the inner face of the widened edge portion of the body. The cover is sealed to the upper edge of the body after some desired liquid or powder is put into the container body.
